Abstract

A Fourier transform microwave spectrometer has been used to make high resolution measurements on the J=1-0 rotational transition for 11 isotopomers of SnO. For the most abundant isotopomer the transition was observed in the v0,1,2, and 3 states. Magnetic hyperfine structure was observed in the transitions for 115Sn16O, 117Sn16O and 119Sn16O. the nuclear spin-rotation constant CI(Sn) has been determined for these isotopomers for the first time and these constants have been related to nmr shielding parameters. a multi-isotopomer analysis, including data from the 120Sn17O and 120Sn18O isotopomers, has been performed on the data. Born-Oppenheimer breakdown parameters were required in the fit and these parameters have been compared to those for the other Sn-chalcogenides.
